| Abstract | Agroforestry parklands are an important agricultural practice in southern Mali where trees such as the Shea (Vitellaria paradoxa C.F. Gaertn) improve soil fertility and crop growth. However, it is not known whether Shea trees can ameliorate Zn-deficient soils or improve Zn uptake from soils of high-Zn, mafic origin.A total of 22 Shea trees preserved in traditional parklands with sorghum (Sorghum bicolor L. Moench) were selected from two soil parent material (PM) types (mafic and non-mafic). Sorghum grain and soil samples were taken along a transect from the bole to 12 m beyond the canopy and analyzed for soil and grain parameters including diethylenetriaminepentaacetic acid (DTPA)-extractable soil-Zn and grain-Zn concentration.Zn-deficient soils were observed with most occurring at non-mafic PM. Mean DTPA-extractable Zn concentrations ranged from 0.55-2.98 μg g$^{−1}$ in mafic soils and 0.34-1.02 μg g$^{−1}$ in non-mafic soils. PM influenced soil available-Zn, but not grain-Zn concentration. Both soil available-Zn and grain-Zn concentrations decreased away from trees with grain-Zn concentration not consistently decreasing across all soils.These results suggest that Shea trees grown in soils derived from mafic PM can improve soil-Zn availability, but that other growth factors are more important in determining grain-Zn content. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
